FEED ATTACHMENT FOR TYPE-WRITING MACHINES.

SPEGIFIGATION forming part of Letters Patent No. 658,946, dated October 2, 1900.

Application filed April 11, 1898. Renewed J'nly'Sl, 1900. Serial No. 25,456. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK P. GoRIN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Feed Attachments for Type- Writing Machines, of which'the following is a specification.

My invention is in the nature of a feed at tachment for use on type-writing and other machines; andmy primary object is to provide a feed device of this nature capable of feeding tothe machine in rapid succession therewith'and within the control of the op-.

'erator for discharging the article to be printed upon from the receptacle into the grasp of the rolls of the typewriter.

In the accompanying drawings, Figure 1 is a vertical sectional view of my feed attachment in the preferred form and a fragmentary View of a type-writer to which it has been applied, the section being taken at line 1 of Fig. 2; Fig. '2, a plan section taken on line 2 of Fig.

1; Fig. 3, a view in front elevation of the detached device, and Fig. 4 a top perspective view of a slide employed for feeding the individual envelops or sheets to the type-writer.

A represents a portion of the stationary frame of a type-writer; B, the traveling carriage, in which are journaled the impressionroll 0 and the feed-roll D; E, the rear trackrod, on which the wheels or rollers E of the carriage move; F, the escapement-rack; G,

the strap which secures the carriage to the spring which moves it, and H a type-carrying lever and its key connection.

I is a receptacle of general rectangular 5o shape for receiving the envelops or such article as it is desired to feed, and J J are two attaching-strips provided at their front ends with downwardly-projecting pins 6 t, which fit into sockets B, with which type-writer carriages ordinarily are provided to receive the studs of the common removable guard and feed plates arranged to support and protect the sheet while it is being written upon. At their rear ends the attaching-strips are pivotally joined, as by pins 3, to the lower rear corner of the receptacle I. To permit the introduction of the envelops, the receptacle is provided with a hinged top r.

The receptacle is preferably formed from light sheet metal and rests upon the supporting and attaching strips in such manner as to project forward, so as to bring its lower at one end to the rear side of the box toward opposite ends of the box and having their free ends projecting in opposite directions and their incurved central portions bearing against the presser-plate at opposite sides of the center line.

The bottom 1" of the receptacle extends forward to near the inner surface of the front side, where it forms, with the front side, a transversely-extending vertical dischargeslot at. I is the front side of the case, having a rectangular portion I cut out from its lower part to allow the point m of the flap m of the envelop to bulge out somewhat more than would be the case if the front side of the receptacle were entirely closed, although it will be understood that in the latter case the device would still be operative, since a space or pocket equal to the'thickness of the blade is left in the lower part of the receptacle, and the forward pressure produced by the springs L L causes the unsealed flap of the'envelop to gap or spring forward from the body thereof into said space or pocket.

slide is held normallyin a raised position by means of springs k, attached to the pins Z, and to pins is, projecting from the top margin of the casing-front. The lower edge of the slide should be beveled, as shown atj in 'Fig. 1, the more readily to engage the flap of the envelop. At the top inner margin of the slide are minute projections h, which serve to engage the top edge of a sheet or card when the device is used for feeding articles of this nature. For feeding envelops the preferred method is to have the lower edge of the slide engage the flap, and of course in this case the projections It would necessarily be dispensed with. If desired, removable pins may be employed, so that the device would be adapted to feed either envelops or cards. I prefer also to provide the slide on its inner surface with a strip of rubber or other frictional material g, as shown in Fig. 4 and indicated by the heavy line in Fig. 1.

The manner of using the device is as follows: Supposing now the projections 72 to be dispensed with, envelops in convenient number are introduced, with the flap forward and upturned, into the receptacle 1, the presserplate being held in its retracted position against the action of its springs. The device being in position on the type-writer, properly centered by reason of its manner of attachment, it is necessary only for the operator to press downward on the handle N, when the beveled surface or knife-edge j of the slide engages the inner surface of the slightlyopen flap m, and when the lower edge of the slide reaches the lower edge of the envelop the envelop is drawn downwardly till its lower edge is brought closely into the entrant angle of the rolls. During this movementof the ejecting-slide the front wall or side of the envelop-case prevents the flap from opening outwardly to an excessive extent, and thereby permitting the knife-edge to slip down past the fold in the envelop. On the contrary, said front side maintains the flap in a position substantially parallel with the ejector-blade, or, in other words, it opposes the tendency of the blade to throw the flap away from the body of the envelop, and hence givesita purchase upon the envelop, whereby it is enabled to draw the latter downwardly. The handle I is then released and the slide is quickly withdrawn under the action of the springs 7a. In the meantime the presser-plate, so far as permitted, has forced the succeeding envelop into the space formerly occupied by the now partially-discharged one. If now the front end of the box, with its protruding envelop, be pressed downwardly, there is sufficient yielding to allow the lower edge of the envelop to be forced between the rolls and into a position to be readily gripped thereby.

The operator now with one hand holds the front end of the box depressed and with the other hand turns the type-writer rolls, thereby causing the envelop to be drawn, properly centered, between the rolls.

Where it is desired to feed sheets or cards, the frictional contact alone may be depended on, or the projections h to engage the upper edge of the sheet may be supplied. In the moderately-slow downward movement the sheet is readily carried downward, whereas in the quick return movement the sheet is not withdrawn. In this case the rolls of the type-writer may be turned while the slide is held depressed and the sheet or card brought thereby between the peripheries of the rolls. It is to be noted that in the drawings in order to keep the lines separate, so as to exhibit the parts clearly, the proper proportions have been departed from somewhat,and this should be borne in mind to understand properly how in the case of cards, as also in the case of envelops, if desired, they may be brought by the action of the slide itself directly within the range of the gripping action of the typewriter rolls. In actual practice the casingwalls are very thin and no difficulty is experienced from keeping the casing exactly vertical. In case the walls should be made thicker it might prove desirable to tilt the casing slightly, so that the slide would enter the angle 19 properly.

One advantage arising from hinging the box I to the attaching-strips J J is that the box may be thrown back to rest upon the rack F, and the type-writer may then be used in the ordinary manner, the box in this position serving as a substitute for the guard and feed plate to hold the paper away from the oiled parts of the machine.

While I have shown the preferred construction of the feed device and the preferred manner of its attachment to the machine, yet it is to be understood that changes may be made both in details of construction and in the manner of mounting the device without departure from my invention. For instance, while it has been deemed desirable to mount the device upon the movable carriage of the machine it is not necessary to do so. The same purpose would be subserved by making the attachment stationary with relation to the main frame of the machine and bringing the carriage to a predetermined position with reference to the attachment at the moment of feeding down a new blank. Also it is not necessary that the attachingstrips be pivotally joined to the receptacle, but they may be fixedly attached thereto. Disadvantages, however, would attend a departure from the construction here shown in either of these respects.

It will be observed that the springs L L press the envelops against the back of the reciprocatory feeder or slide when the latter is in normal position and cause the unsealed flap to move past the vertical plane of the slide or to gap, so that the feeding edge of the slide may enter between the flap and the body of the envelop to engage the fold thereof and discharge the envelop. The slide moves along the back of the envelop at the feeding operation, but without moving the envelop until it engages the fold thereof. As it is desirable that the envelops should normally press against the back of the slide the latter is of such width that when in normal position its lower edge stands just above the point of the flap, so that the extent of the feeding movement of the slide relatively to the envelop is a trifle greater than the width of the flap and preferably much less than the width of the envelop Many changes may be made in the details of construction-and arrangement within the scope of the invention, and my improvements may also be adapted to feed envelops to other kinds of machines.

What I claim as new, and desire to secure by Letters Patent, is-

1. A device for feeding envelops, or the like, to a type-writer, comprising a receptacle for articles to be fed provided at its lower forward part with a discharge, forwardly-extending attaching-strips upon which the bottom of the receptacle rests and which are pivotally connected with the lower rear portion ofthe receptacle and supplied withattaching means, a spring-held presser-plate movable within the receptacle, and a slide at the front end of the receptacle for effecting the discharge, substantially as and for purpose set forth.

2. The combination with a type-writer and the impression and feed rolls thereof, of a feed attachment, comprising a receptacle provided at the front end with a transversely-extendin g discharge-slot in the entrant angle between said rolls and close to the line of contact between said rolls, means within the receptacle for advancing the articles to the front end of the receptacle, means for attaching the receptacle to the type-writer, and a spring-held discharge-slide connected with the front end of the receptacle and provided with a handle, and operating when depressed to feed the article directly into said angle whereby it may be drawn between the rolls without the aid of further mechanical agency, substantially as and for the purpose set forth.

3. The combination with a type-writer, of an envelop-feed attachment, comprising a receptacle for receiving the envelop-flap edge downward provided at the front end of its bottom with a discharge-slot, a front'end for the receptacle provided with a recess to permit the flap of the envelop about to be discharged to protrude slightly, a slide movably connected with the front end for engaging said flap and efiecting the discharge, and

means for yieldingly holding the envelops on edge and pressing them into contact with said slide, substantially as and for the purpose set forth.

4. In an envelop-feeding mechanism, the combination of an envelop-receptacle provided with a discharge opening, a slide mounted in said receptacle, and means for pressing'the en velops against the back of said slide when the latter is in normal position and causing the unsealed flap to move past the plane of the slide, so that the feeding edge of the slide may enter between the unsealed flap and the body of the envelop to engage the fold thereof and discharge the envelop.

5. In an envelop-feeding mechanism, the combination of an envelopreceptacle provided with a discharge-opening, a reciprocatory feeder provided with a knife-edge and arranged normally above the free edge of the flap of the foremost envelop, and a pressure device, the construction and arrangement being such that at the feeding movement said knife-edge is introduced between the flap and the body of the envelop to engage the fold thereof and discharge the envelop.

6. In an envelop-feeding mechanism, the combination of an envelop-receptacle, means for causing the unsealed flaps of the envelops to gap, and a slide constructed and arranged to move along the back of the envelop at the feeding operation without moving said envelop until it engages the fold of said envelop, whereupon by a further movement it carries the latter out of said receptacle.

7. In an envelop-feeding mechanism, the combination of an envelop-receptacle and a feeding device constructed to have a feeding movement relatively to each envelop, the extent of said relative movement being greater than the width of the flap, but less than the width of the envelop, the construction and arrangement being such that the feeding edge of said feeding device enters between the flap and the body of the envelop to engage the fold thereof and eject the envelop.

8. In an enve10p-feeding mechanism, the combination of an envelop-receptacle having a discharge-opening, a slide, means for pressing the envelops toward said opening, means for causing the unsealed flaps of the envelops to gap, and an ejecting-slide adapted to enter between the said flaps and the bodies of the envelops.

9.In an envelop-feeding mechanism, the combination of an envelop receptacle, an ejecting-slide constructed to enter between the unsealed flaps and the bodies of the envelops, and means opposing .the slide for holding the flap substantially parallel therewith during the ejecting operation.
